Answer:

x - 5y - z = 14

(-x)              (-x)                (subtracting x from both sides)

-5y - z = 14 - x

(+5y)       (+5y)                (adding 5y to both sides)

-z = 14 - x + 5y

(-z = 14 - x + 5y) * (-1)      (multiplying both sides by -1 to make z positive)

z =  -14 + x - 5y                (Answer :))

A. Find x. The figure is not drawn to scale.b. Is the triangle equilateral, isosceles, or scalene? Explain

Answers

Based on the given figure above, we can conclude that the triangle is an isosceles triangle. By definition, an isosceles triangle is a triangle that has at least two equal sides. Since this is an isosceles triangle, 8x-10 =6x. Now we can solve for x. So,
8x-10 =6x
8x-6x = 10
2x =10
x= 5.
Therefore, the value of x in the figure is 5. Hope this is the answer that you are looking for.

How are fractions and decimals related

Answers

A fraction is a short way to write a division problem. When you see a fraction, it means "the top number divided by the bottom number". When you actually DO the division, the answer is the decimal that's equal to the fraction.
because fractions and decimals represent the same value just in a different form

The sycamore grove contains 30 sycamoretrees. That's 75 percent of all the sycamore
trees in the park. How many sycamore trees
are in the park?
​

Answers

Answer:

40 sycamore trees

Step-by-step explanation:

We can use the following equation to calculate the total number of sycamore trees in the park:

75% of Total sycamore tree = 30 sycamore tree

0.75 of Total sycamore tree = 30 sycamore tree

\textsf{ Total sycamore tree = $\sf (30)/(0.75) $ sycamore tree}

\textsf{ Total sycamore tree = $\sf 40 $ sycamore tree}

Therefore, there are 40 sycamore trees in the park.

Let’s assume that the number of sycamore trees in the park is x. According to the problem statement, 30 sycamore trees make up 75% of all sycamore trees in the park. This can be expressed as:

30 = 0.75 * x

Solving for x, we get:

x = 30 / 0.75

x = 40

Therefore, there are 40 sycamore trees in the park.
